Geotrochus is a genus of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Trochomorphidae.
General characteristics
The shell has a trochiform shape and is an imperforate structure. The whorls are flattened. The upper surface is covered with numerous raised spiral lirae. Conversely, the lower surface is shining and is finely striated transversely. Finally, the margins of the aperture are acute, and they are not reflexed.
